Improvement in tube-wells



me we Letters Patent No. 96,854, dated November 16, 1869.

vIMPROVEMENT IN TUBE-WELLS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom itmay concern! l Be it known that I, ASA WATERS, of Mobile, in

`:the county ofMoble, and State of Alabama, have invented a new and useful Improvement in Tube-Wells; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the saine, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to new and useful improvements in tube or drive-wells, and consists in covering the perforated well-tube with wire cloth, and in protecting the wire-cloth covering with a perforated metallic shield, as hereinafter more fully described.

1n the accompanying drawing- Figure l represents the lower portion or section of a well-tube constructed according to my invention.

Figure 2 is a cross-section of iig. 1, through the line x x. v

Similar letters of reference indicate corresponding parts.

A represents the perforated well-tube, the interior of which is left entire or unobstructed.

B is the wire cloth by which the tube A is corered.

C represents the perforated shield by which the wire cloth B is protected.

The lowerl section of a tube-well usually contains an interior tube, covered with a screen of wire cloth,

so that the tube itself forms the shield. By dispensing with the inner tube in my present invention, l leave the well-tube free and unobstructed, and avoid a diiculty which has always been experienced in tubewells constructed on lthe old plan, that is, the diiicnlty of keeping the water-passages unobstructed by reason of earth and clty which are forced through the orifices.

By my arrangement, the earth or clay enters 'insuch minute particles that they are readily washed out by the VIflow of water.

D represents the collar on the lower section, into which the next section of the tube is secured.

I claim no novelty in regard to this, nor to the Witnesses:

HARRY PILLAUs, PHILIP I. MAY.
